| Abstract/Contents: | Presents a study conducted to "determine whether superior heat tolerance in the thermal bentgrass was associated with metabolic factors regulating heat-induced leaf senescence, specifically changes in the three major senescence-related hormones (ethylene, ABA, and cytokinins)." Details methods and materials used in the study, stating that "creepeing bentgrass (cv. Pencross) plugs were collected from field plots at Hort Farm II, Rutgers University, [New Jersey]. Plants of A. scabra, originally collected from geothermally heated areas in Yellowstone National Park, Wyoming, were propagated in greenhouses at Rutgers University...Plants of both species were exposed to 35°C [celsius]/30°C (day/night, high temperature) or 20°C/15°C (68°F [Fahrenheit] day/59°F night, optimum temperature) for 35 days in controlled-environment growth chambers." Reports that "heat stress caused decline in turf quality in both bentgrass species, but the decline occurred three weeks later in the thermal bentgrass than creeping bentgrass. Chlorophyll and carotenoid content of the thermal bentgrass exposed to heat stress were maintained at the optimum temperature level for approximately 14 days without any significant decrease from 21 and 28 days, respectively. The decline in turf quality, chlorophyll, and carotenoid content was less severe for the thermal bentgrass than creeping bentgrass." Concludes that these studies "suggest that foliar application of cytokinins or ethylene inhibitors may be useful to suppress or delay leaf senescence and ultimately improve turfgrass performance during summer months." |
